This was a great discussion. It was especially nice to have Bertrand during the discussion. If we had any questions about how or why Microsoft did something, we could ask him. I was happy to hear that one of the reasons they chose jQuery was because they didn’t want to write their own CSS selector functions for MS AJAX. It’s nice to see that Microsoft sees the benefit in not always reinventing the wheel. Now, any new features or improvements that Microsoft would have made to their own selector engine can be contributed towards jQuery, making it a better product for all of us.
